2020-12WG GRI Earth Magnets Alarm Door Sensor

Review GRI 2020 12wg Pc 12wgb Rare Earth Magnets 3/8 Inch Alarm Door Sensor

The GRI 2020-12WG N2020-12WG-B Earth Magnets 3/8 Alarm Door Sensor is a high-performance magnetic door sensors designed for securing various applications. The sensor consists of two parts: a magnet and a reed switch. The powerful Earth Magnets, model GRI 2020-12WG, are fabricated from neodymium, a rare earth material known for its strong magnetic properties. This magnetic pair comes with anodized covers in a black finish for an attractive and durable look. Their size is 3/8 inch in diameter and 1/8 inch thick, providing an ideal magnetic field for triggering the reed switch.

The second component, the N2020-12WG-B Reed Switch, is designed to work with the Earth Magnets. It has a brass housing and two additional terminals for power and normally open contacts. When the powerful neodymium magnets come within proximity to the reed switch, the action of the switch closes the contacts and completes the electrical circuit.

This GRI 3/8 Alarm Door Sensor features a versatile design appropriate for various applications. It can be implemented in alarm systems, door monitoring systems, industrial automation, and other similar applications. The use of both high-quality Earth Magnets and a reliable Reed Switch ensures that the sensor can withstand wear and tear and deliver consistent performance over a long period.

Overall, the GRI 2020-12WG N2020-12WG-B Earth Magnets 3/8 Alarm Door Sensor is a robust, reliable, and highly sensitive magnetic switch that can be used in a vast range of applications where door and window monitoring, detection, and security are a priority.
